The 26-year-old sealed an £8m move to the north London side on Thursday, and the Spanish defender will compete with André Santos and Kieran Gibbs for the left-back spot.
Monreal moves to The Emirates less than six months after his former Malaga team-mate Cazorla joined Arsenal, and the Spain international is hoping to match the playmaker’s impact at the Gunners.
“Yes, I spoke to Santi, we had a long conversation about things,” Monreal told Arsenal’s website.
“I asked how things were here and he only had very positive things to say. He said that Arsenal was a massive club, the people are great and it’s really just a big family. He only had good things to say. I am sure we can be successful this season and I am really looking forward to the challenge.
“Yes it does [help that Cazorla has been a success]. It helps that I’ve been able to share a dressing room with him at Malaga, that everything’s gone well and that the people here have been incredible in welcoming me.
“As there’s a familiar face in Santi, I’m a lot calmer about things. Having shared a dressing room with someone who’s already made this journey is a good feeling. Now it’s my turn and I can’t wait to follow in his footsteps.”
Monreal also rubbished claims that he joined Arsenal because of the club’s Spanish connection, insisting the Gunners are a “massive club”.
“To be honest, when I was given the option to come here I went for it because it’s a massive club,” he added. “I didn’t even have to think about it.
“Of course, there are Spanish players here and a lot of youngsters, which this club is known to attract. I’m delighted to be able to train and play with those guys and I hope my stay here will be the best it possibly can.
“I’ve watched loads of Arsenal games and there have been legends that have played for this club. I know everything I can from watching the television and from what Santi has told me in this relatively short period of time.
